investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they have a good

Introduction – Lab Report What is a Chemical Reaction? A chemical reaction is a change in matter that produces one or more new substances. A chemical change or reaction occurs when bonds are broken and new ones are formed. The formation and dissolution of these bonds are dependent upon environment changes. Even without the usage of microscopes‚ chemical reactions are usually apparent to the naked eye. The two main kinds of changes that one can observe are the formation of new substances and changes in energy

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs

BIO 211 Lab Section 11 February 15‚ 2012 Effects of Temperature on Enzymatic Activity Abstract Temperature is a measure of kinetic energy. As this movement increases‚ collision rate and intensity‚ and therefore reaction rates‚ increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction

The Grignard Reaction Abstract Through the use of the Grignard reaction‚ a carbon-carbon bond was formed‚ thereby resulting in the formation of triphenylmethanol from phenyl magnesium bromide and benzophenone. A recrystallization was performed to purify the Grignard product by dissolving the product in methanol. From here‚ a melting point range of 147.0 °C to 150.8 °C was obtained. The purified product yielded an IR spectrum with major peaks of 3471.82 cm-1‚ 3060.90 cm-1‚ 1597.38 cm-1‚ and 1489

investigation was to investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate is added
